Add two new course types to the Course Type picklist

[rustynwac]

Description

Adds two new course types to the shared Course Type picklist:

• Intro to Avalanches Field Course (intro-to-avalanches-field-course)
• Level 1 + Rescue Combined (level-1-rescue-combined)

courseTypesData in src/constants/courseTypes.ts is the single source of truth for course types — the Courses courseType select, the Providers "Approved Course Types" select, the public course-type filter, the embed generator, and the provider-published email all derive their options from it. Appending the two entries there makes them available everywhere at once. The options are global to all avalanche centers (course types are not tenant-scoped), which is the intended behavior.

The new entries include label and value only — no description. The description field on CourseType is optional and is rendered nowhere (every consumer maps the data down to { label, value }), so adding description copy would be invisible dead data.

Key Changes

• Append two new entries to courseTypesData in src/constants/courseTypes.ts (existing six entries untouched).

How to test

1. In the admin panel, create or edit a Course and confirm both new options are selectable as the Course Type (subject to the provider's approved-types filtering that already applies).
2. Edit a Provider and confirm both new options are selectable under "Approved Course Types".
3. On the public course listing, confirm the "Course Type" filter shows both new options.

Screenshots / Demo video

N/A — picklist value addition, no visual/layout change.

Migration Explanation

No migration required. The stored columns for these select values (courses.course_type and providers_course_types.value) are plain text with no enum/check constraint, so new option values are accepted without a schema change.

Future enhancements / Questions

• CourseType.description is currently carried in the constant but rendered nowhere. If descriptions should ever be surfaced (admin field help text, public filter tooltips, etc.), that would be a separate change — and the two new types would need description copy at that point.
